Summary

Fixes #

Service Instance Deletion

Occurred changes and/or fixed issues

• Implement trailhand modal for service deletion.

Technical notes summary

• Refactored some of the logic adding during namespace deletion to be a reusable util. This util accepts the rows, and some config objects for properties to add or override, and then will return the updated rows
• This is because in order to use the trailhand modal and not the default rancher flow we need to override the promptRemove action on the row
